Summary
A flaw was found in the Update User Locale required action of the Keycloak identity and access management solution. When this action is ordered before the Configure OTP action in a realm, the system may fail to enforce mandatory multi-factor authentication enrollment during the login process.
This issue allows an attacker with a valid password to access an account without setting up the required one-time password (OTP) credential. The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate, given that exploitation requires a specific and non-default configuration of required action ordering within the realm.
Successful exploitation allows an attacker to bypass mandatory OTP enrollment and gain access to a user account using only a password. The vulnerability's root cause is an early exit in the required-action processing loop due to missing status returns in the Update User Locale action handlers.
Weakness: CWE-287. Affected Red Hat products: Red Hat Build of Keycloak; Red Hat Single Sign-On 7.
Red Hat does not currently list a fixing RHSA for this CVE.
